This is likely dependent on location. Here on the central coast under 50 is “cold” and over 70 is “hot.“ my relatives in Oregon and Minnesota have a bit different thresholds. Ha.
My Mastodon, SRAM DOT 5.1 brake fluid brakes, TranzX dropper and Wrathchild studded tires run tubeless, all function flawlessly in temps much colder than minus 15 C. Unfortunately, my feet, hands and face no longer do. I draw the line these days at minus 15 for anything beyond a short commute. It’s just not that enjoyable any more for me, battling the cold.…lots of people i know ride snow down into the -15c range on fat bikes w studs. mechanical brakes, etc. ridgid suspension necessary as they dont make great forks designed for -15c temps. here the snow remains fairly consistent ride to ride over the bulk of winter.
Around here (eastern PA) we'll do night rides in single digits fairly frequently.For those riders in climates less hospitable than SoCal, what if any is your threshold temperature for riding?
Yikes! You mean like this? LOLi run shorts down to about 12 celcius, then long pants down to about 5 Celcius. after that its not as much fun and over night temps will freeze the ground. so i dont like riding on it as its traction goes way off and hitting the deck has higher consequence. snow and ice builds in darker corners and its just treacherous.
